Description

[Detailed Description of the Invention] Conventionally, kitchen waste in ordinary households is stored temporarily in a basket installed in the sink, then placed in a plastic bag, etc., and stored in an outdoor garbage container until the garbage collection truck comes around. This was common, especially during the summer, when it rotted and emitted a strange odor, making it extremely unsanitary.

In addition, disposers and the like have not yet become widely used in general households in the current situation where sewage treatment facilities are not fully equipped.

The present invention eliminates the above-mentioned drawbacks of conventional kitchen waste processing methods and kitchen waste processing machines, and therefore aims to provide a device that heats and dries generated kitchen waste under reduced pressure.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Reference numeral 1 denotes a vacuum heating container section, which includes a container 3 having a drainage/decompression port 2 at the bottom and an opening 3a at the top, a lid 4 that airtightly closes the opening 3a of the container 3, and a heater for heating the container 3. 5, and a thermostat 6 that detects the temperature of the container 3 and controls the heater 5.

7 is a flowing water type wave pressure device (aspirator), which is composed of an outer tube 8 through which flowing water passes, and a nozzle 9 that opens into the small diameter portion 8a of the outer tube 8.

Further, the flowing water introducing portion 8b of the flowing water type wave pressure device 7 is connected to a solenoid valve 10.
The running water discharge part 8C is connected to a sewer pipe via a backflow prevention device 11, and the other end 9a of the nozzle 9 is connected to a reduced pressure heating container via an electromagnetic switching valve 12. It is connected to the drainage and decompression port 2 of section 1.

The solenoid valve 10 is opened when this device is used, and the flowing water type wave pressure device 7 is opened.
, through which water flows, and when not in use, it closes to stop the flow of water.

The backflow prevention device prevents sewage from flowing back when the device is not in use, and the electromagnetic switching valve 12 allows the drain and pressure reduction port 2 to communicate with the nozzle 9 when the device is in use; , the drainage/depressurization port 2 and the bypass pipe 13 supplying air in the direction of arrow B are communicated to maintain the pressure inside the container 3 at atmospheric pressure when the device is not in operation, and to facilitate opening and closing of the lid 4.
Water from thrown kitchen waste is directly discharged into the sewage system.

The kitchen waste drying device of the present invention is constructed as described above, and its effects will be explained below.

The kitchen waste is put into the container 3 and the lid 4 is put on to seal the opening 3a.

The heater 5 is energized to heat the kitchen waste inside the container 3.

Drainage of kitchen waste and bad smells are discharged from the drainage and decompression port 2 of the container 3.
It is extracted from the nozzle by the pressure reducing action of the flowing water wave pressure device 1.

Drainage water and foreign odor from kitchen waste mixed in the high-speed water flowing through the outer pipe 8 are discharged from the backflow prevention device 11 to the sewer in the direction of arrow C.

As described above, the kitchen waste drying apparatus of the present invention is capable of heating and drying kitchen waste, and discharging waste water and odor from the kitchen waste to the sewage water by the venturing action of the flowing water type corrugated pressure device 7.

As explained above, the kitchen waste drying apparatus of the present invention has a heating device and a drain/pressure reducing port, a container that is opened and closed by a lid, a flowing water wave pressure device (aspirator) connected to the drain/pressure reducing port, and a container that is opened and closed by a lid. It is characterized by being equipped with an atmosphere-side drainage section to sewage, etc., and a switching valve that selectively communicates the drainage and pressure reduction port with the flowing water type wave pressure device or the atmosphere-side drainage section, so that the pressure inside the container is reduced. Combined with the heating effect of the heating device, it is possible to dry in a very short time and prevent spoilage due to the heat sterilization effect.Furthermore, since all processing is done inside the container, there is no odor during processing. Since the process is very hygienic and the pressure reducing device uses a flowing water type, there is no need to worry about oil stains that occur with rotary vacuum pumps, and therefore there is no need to worry about oil changes. There is no character.

Furthermore, by connecting the drain/pressure reducing port to the atmospheric side drain via the device's non-operating switching valve, the inside of the container becomes atmospheric pressure, making it easy to open the lid and take out the dry food waste inside. It can provide very flexible options in many aspects.
